Simulation Studies on Muon Neutrino DIS Analysis at the SND@LHC Detector — Andrew Conaboy, Heiko Lacker, •Tilly Smith, and Eduard Ursov — Humboldt University Berlin

The SND@LHC experiment, located 480m downstream from the ATLAS interaction point at the LHC, aims to detect high-energy neutrinos originating from proton-proton collisions at the LHC. This standalone experiment targets the otherwise inaccessible pseudo-rapidity region of 7.2 < η < 8.4 and with the data taken during the first year of running in 2022 has successfully identified 8 νμ CC candidates with a significance of seven standard deviations. An in-depth simulation of the detector environment as well as the muon neutrino deep inelastic scattering (DIS) interaction is being developed to further enhance this significance level.

This talk gives an overview of the developed simulation as well as its performance on MC simulated data for both signal and background processes. Details on the applied selection cuts, tracking algorithm and analysis methods are given as well as a comparison to previous performance studies. To improve the background rejection, we study the distributions of the interaction point, shower width and position, and muon angle after interaction for simulated signal and background samples.
